BALL-BEARINQ'WHEEL.

SPECIFICATION forming part of Letters Patent No. 531,101, dated December18, 1894.

Application filed December 11,1893. $erial No. 493,330. (No model.)

To all whom it may concern.

Be it known that I, HALLAM F. GoArEs, residing at Cambridge, in thecounty of Guernsey and State of Ohio, have invented certain new anduseful Improvements in Ball-Bear ing Wheels, of which the following is aspecification.

My invention relates to improvements in ball bearing wheels and it hasprimarily for its object to provide a wheel of this kind, simple inconstruction, of few parts, easy of manufacture and put together, inwhich the use of bolts, gaskets, caps, nuts and other loose. parts nowgenerally used on wheels of this kind, is dispensed with.

It has also for its object to provide a construction which will saveoil, which will reduce the friction to the minimum, in which the axlewill be protected and in which the parts are so arranged, as to give theinside of the wheel the same wearing qualities as the outside.

With other objects in view which hereinafter will be referred to, theinvention consists in the peculiar combination and novel arrangement ofparts, which will be first d'e-' scribed in detail and then specificallypointed out in the claims, reference being had to the accompanyingdrawings, in which Figure 1 is an inner face view of a car wheelconstructed in accordance with'my invention. Fig. 2 is a verticalsection of the same taken on the line 2-2 Fig. 1, and Fig.{ 3 is a sideview of the filler or bearing hub.

Referring to the accompanying drawings A indicates a car wheel formedwith a central hub or socket portion B, having a. chamber B, the innerportion of which terminates in a straight bearing wall b formed by theinner wall or face of the wheel, while its outer end extends flush withthe outer face of the wheel, such wallb having a central aperture 1)through which the axle spindle is adapted to pass but not contact withfora purpose presently, explained.

By referenceto Fig; 2 of the drawings it will be observed the bearingface of the chamber B extends,horizontally from the wall b outward, suchconstruction providing an unobstructed socket in which the filler oraxle bearing 0 can be readily inserted or removed,

aperture 0 adapted to receive a lock pin E,

which, when the parts are assembgd passes through a coincident aperturedin the axle .and locks the filler thereto.

In the peripheral face of the filler O are formed two parallel grooves OO, which are spaced sufficiently apart, and at each side of its centralvertical bearing line, as to give the wheela steady bearing and preventit from wabbling the grooves being also of a sufficient'depth-to formperfect guides for the bearing balls F, which are fitted in the grooveswhen such filler is adjusted to bring the grooves in linewith thebeveled portion b of the chamber B. It will be noticed that thesegrooves are placed with reference to the wheel, so as to sustain theweight of the'car from a point of co ntacfvertically from the track tothe center of the] bearing axle. 'To hold the filler from workingoutward, the axle D is formed with a shnoaulder d, which is adapted asit moves late lly outward, to engage the wall or inner face of thewheel, and when such axle moves inward the reduced portion' or boss 0engages the inner face of such front wall as shown; it being obviousthat by forming a boss 0 on the filler as shown the friction between theends of the filler and the inside of chamber D will be much reduced.

In practice the aperture 1) through which the axle spindle passes ismade of a diameter sufficiently to allow such spindle to pass throughwithout engaging the aperture, thereby holding the wheel properentirelyfree from contact with the axle and placing the entire bearingstrain on the filler.

In cases where the improved wheel is made entirely, in accordance withmy invention, I use aspindle formed non-circular, to save expense ofswaging and turning axle bearing round, but where wheels are made toreplace those running on round axles, such axle is connected by a pin orother means with the 5 filler.

So far as described it will be readily seen that by arranging thefiller, the balls and the receiving chamber as shown, no special capplate or similar means are needed for holding to the balls in place.Furthermore as the filler is held stationary with the axle, which isheld from turning, and forming the axle passage of the wheel largerindiameter than the axle the bearing of the wheel will be entirely on r 5the balls in the lower portion of the grooves and on the filler onpoints below the horizontal line drawn through the center of the filler.It will also be noticed that as the wheel turns about the filler and asthe balls are spherical, such balls will continuously turn in thegrooves and thereby wear uniformly, and in case the lower face of thegrooves become worn, it is only necessary toremove the pin E and turnthe filler half way around on the axle, which adjustment brings intoposition an entirely new bearing for the balls passing under the weightof the load between the filler and point of contact of the balls againstthe inside of the lowest point of the chamber B. 0 By dispensing with acap plate, the filler can be quickly inserted in position in the chamberB and readily removed by drawing the pin E.

Having thus described myinvention, what 3 5 I claim, and desire tosecure by Letters Patent, isi 1. As an improvement in car wheels, the

combination with a Wheel having its hub portion formed with a centralsocket or chamber, having its base or inner wall centrally aper- 4otured to receive the axle, and a nou-rotatable axle projected into suchchamber, of a filler of slightly less diameter than the chamber, adaptedto he slid endwise therein, said filler having a plurality of annulargrooves; the bearing balls fitted therein to engage the wall of suchchamber, and means for adjustably connecting such filler on the axle,whereby it will be held from turning when fitted thereon and whereby itsupper and lower faces can be turned to diametrically opposite points asthe lower or bearing face becomes worn, all substantially as shown andfor the purposes described.

2. As an improvement in car wheels the 5 5 combination with the Wheel A,having a central socket or chamber B having in its base or rear wall anaperture 19' of a larger diameter than the axle, and the axle projectedinto such chamber having a collar d,abntting the face of the wheel, andits end apertured, of the filler 0 held on the axle said filler having acentral reduced portion a at one end and a reduced apertured portion aat the other, a key fitting the aperture and the coincident aperture inthe axle, and provided with annular grooves c, and the balls F fittingsuch grooves all arranged substantially as shown and described.
